We did a special pen for the Chicago Pen Show this year, and have a few pieces left.
These feature the Harlequin pattern, with the diamonds filled with matte red, blue, and green. The pens are also engraved on the cap with CPS 26. Just six pieces left, so while supplies last.
Takes #6 nib, comes with converter, zippered pouch, lifetime warranty, etc.
$180 for the pen, nibs start at $25.
